Answer:
Step-by-step explanation:
l = 4m = 400 cm
w = 3m = 300 cm
Volume = 720000 cubic cm = 720000
length * width * height = 720000
400 * 300 * height = 720000
height = 720000 / 400 * 300 = 72/12 = 6 cm
X/3-5=y
add 5 to both sides
x/3=y+5
now multiply both sides by 3
x=3(y+5)
which means
x=3y+15
h(t) = -16t2 + 64
Time to reach ground:
h(t) = 0
-16t2 + 64 = 0
Solve for t, keeping only the positive solution.
Time to fall 36 ft:
Since it is dropped from 64 ft, its height after falling 36 feet is 64-36=28 ft.
28 = -16t2 + 64
-16t2 + 36 = 0
